7.2.2
The interface circuit between the MCU in the emulator and the user system has a signal delay of about 8 ns due
to the user system interface cable and it includes pull-up resistors. Therefore, high-impedance signals will be
pulled up to the high level. When connecting the emulator to a user system, adjust the user system hardware to
compensate for propagation delays.
The following diagrams show the equivalent circuit examples of the interface signals.
Default:
Mode Pins (MD2, MD1, and MD0): The mode pins are only monitored. The CPU mode depends on the High-
performance Embedded Workshop settings.
RESET and NMI: The RESET and NMI signals are input to the MCU through the emulator control circuit. The
rising/falling time of these signals must be 8 ns/V or less.
